Around 90 percent of Britain's top companies have no women bosses, according to a parliament report. 

A parliament written answer obtained by former Treasury spokesman Matthew Oakeshott said there was no woman executive director in 310 of the top 350 companies in the country, The Sun reported.

Only 43 women are working in other senior roles. Oakeshott, a Liberal Democrat member of the House of Lords, said: "Britain's big businesses are an old boys' club."
